All TRUE rack fanatics know that it's not about sound, versatility or any of that wussie stuff.
It's all about FLASHY LIGHTS! *The more the better. *That's why we love rack tuners
But seriously, if you ARE thinking about sh*ll
ing out the cash for a rack tuner, get a GOOD one. *There are much cheaper alternatives to tuning your guitar, and it's only really worth the difference if you either:
a) Really like flashy lights.
b) Want a
strobe tuner (which is excellent, but not cheap)
